Rocker Dave Grohl ripped pop star Britney Spears while he was sitting in as cohost on "Chelsea Lately".
The Foo Fighters frontman said, "She kinda seems dead inside. There's nothing behind her eyes, there's nothing in her boobs anymore."
Of course, her fans aren't taking the comments lightly.
One wrote, "As one of rock's truly solid guys, Grohl knows better than this."
